*I'm going to reply to three different people in this one post, so if you're one of those people, please make sure to scroll down and find the section relevant to you.
taliosfalcon: like others, you may want to see if you have better luck connecting under wicd (see post #178 for instructions on installing it). This may do the trick, especially if you're trying to connect to a secured network. The way that Network Manager (the program that Ubuntu uses by default to connect) does WPA negotiation is sort of weird, and sometimes wicd does it more successfully.
Another possible solution for you is to install native drivers for your card instead of ndiswrapper. I helped a friend get the wireless working on her Wind--same wireless card as yours--and the native driver, r8187b, works quite well. To install those drivers, run these commands (make sure you are online via ethernet first):
At this point, provided you haven't received any error messages, your card should be up and running until the next reboot. If this works, we can make the installation permanent so that the wireless will come up automatically.
sudo apt-get install build-essential
tar -xzvf rtl8187se_linux_26.1023.0928.2008.tar.gz
sudo modprobe -r ndiswrapper
[note: if the process above fails, you can try an alternate installation method using Debian packages by running these commands:
This should work for Ubuntu 8.10.]
sudo dpkg -i linux-rtl8187se-*.deb
etherealethel: I'm afraid I don't have anything definite to tell you, but I found this post, which says that running this command solves the problem of the WG111v2 not connecting:
Does it help? If not, please post the output of this command:
sudo iwconfig wlan0 rate 5.5M
husky55: try running these commands. I made a typo previously which probably screwed things up (I'll edit the original post to fix it), and the script that you created is probably not really running at boot. But running this once should fix that:
The 'defaults' part is what I forgot before.
sudo chmod +x wifi-fix.sh
sudo update-rc.d wifi-fix.sh defaults
